Both are excellent heads... that being said, I shoot Magnus 1's myself. I like wide 2-blades.
Couple of years ago I had 4 shots at 4 critters with 4 hits (one was a spine shot with a quick follow up into the lungs), with a total tracking job of 105 yards.
One 11 point buck and two does in Texas (Solana), 12 to 28 yards perfect flight to their mark.
Heads sharpen easily, and do massive damage when they get there. Three of the arrows were sticking in the ground and the 4th (28 yards) was to the fletchings about 2" above the heart. Ribs, spine, and off shoulders hit. They were shot out of that Shawnee, 60# @ 29".
